Remote E-Corner Steering for Tight-Space Vehicle Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle steering technologies, particularly those utilizing e-corner modules, do not adequately address the challenges drivers face when entering or exiting vehicles in tight spaces, such as after crab driving or when parking environments change.
Innovation Solution
A system and method for vehicle steering that allows remote control of vehicle corner modules using a user terminal, enabling independent wheel steering and various driving modes like crab, pivot turn, and zero turn, even when the user terminal is dismounted, with features like departed driver rescue and exit maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the driver uses crab driving or zero turn driving to park in tight spaces, then the vehicle can be positioned in narrow areas, but the driver cannot exit or enter the vehicle due to insufficient space
Solution Approach 1:
The system separates the driver's control function from the physical presence requirement by enabling remote control through a user terminal. The driver can control the vehicle's corner modules from outside the vehicle, allowing the driver to exit tight spaces after positioning while maintaining full control capability.
Solution Approach 2:
The user terminal acts as an intermediary between the driver and the vehicle's steering system. The driver interacts with the terminal (smartphone or remote control) which communicates with the corner modules, enabling indirect control that eliminates the need for physical presence inside the vehicle.
2Ease of operation
If the user terminal is mounted on the steering module for normal driving, then the driver has full control, but the driver must be inside the vehicle to operate
Solution Approach 1:
The system dynamically adapts its control interface based on the operational context. When the user terminal is mounted, it provides the full steering control interface for normal driving. When dismounted, it switches to providing only corner module control commands, allowing the driver to operate from outside the vehicle when needed.
Solution Approach 2:
The user terminal serves multiple functions depending on its mounting state: it can be used as a full steering control interface when mounted on the steering module, or as a remote control for corner modules when dismounted. This multi-functionality enables the system to adapt to different operational scenarios.
3Adaptability or versatility
If the parking environment changes after the vehicle is positioned (e.g., narrow parking on both sides), then the vehicle may block pathways, but the driver cannot reposition the vehicle from outside
Solution Approach 1:
The system enables the driver to independently reposition the vehicle from outside by using the user terminal to control the corner modules. The driver can perform self-service repositioning without needing assistance from others, maintaining the ability to adapt to changing environments.

AI summary
A system for steering a vehicle, and a method therefor are provided. The system includes a steering module, a user terminal mountable on and dismountable from the steering module, a vehicle corner module provided for each of wheel of the vehicle so that steering of each of the wheels may be independently operated, and a processor to independently control steering of each of the wheels through the vehicle corner module based on steering information received from the user terminal.
